Builders broke ground on more single-family homes and apartments in June, as the home-building industry tried to shake off a historically bad spring.
The Commerce Department says builders began work on a seasonally adjusted 629,000 homes last month, a 14.6 percent increase from May.
Still, that's roughly half the 1.2 million homes per year that economists say must be built to sustain a healthy housing market.
Stock futures rose after the report was released.
Much of the increase came from a surge in apartment construction, a volatile part of the industry.
That jumped 31.8 percent last month.
Single-family home construction rose a more modest 9.4 percent.
Building permits, a gauge of future construction, increased 2.5 percent.
June's building pace was the best showing since January and single-family home construction saw the biggest monthly increase since June 2009, when the recession ended.
Though new homes represent just 20 percent of the overall home market, they have an outsize impact on the economy.
Each home built creates an average of three jobs for a year and generates about $90,000 in taxes, according to the National Association of Home Builders.
Builders are nearly 31 percent ahead of the 477,000-per-year pace from April 2009, which was the lowest point on records dating back to 1959.
Still, they are down roughly 73 percent from their peak of nearly 2.3 million homes in January 2006.
Cash-strapped builders are struggling to compete with deeply discounted foreclosures and short sales.
A short sale is when lenders allow borrowers to sell their homes for less than what is owed on the mortgage.
New-home sales fell in May to a seasonally adjusted pace of 319,000 homes per year.
That's far below the 700,000 homes per year that economists consider healthy.
One reason is that previously occupied homes are a better deal than new homes. The median price of a new home is more than 30 percent higher than the median prices for a re-sale.
That's more than twice the markup in healthy housing markets.
Loans are also harder to get. Most private lenders are requiring 20 percent down payments and higher credit scores for the best rates.
The weak housing industry is also holding back the U.S. economy.
In past modern-day recessions, housing accounted for 15 to 20 percent of overall economic growth. This time around, between 2009 and 2010, housing contributed just 4 percent to the economy.
In the past month, President Barack Obama said the housing market has "been most stubborn to us trying to solve the problem." And last week Federal Reserve Chairman Ben Bernanke said the troubles facing home construction and sales were more persistent than previously thought.
The builders' trade group said Monday that its survey of industry sentiment rose to 15 in June.
That's after a May in which builder outlook hit its lowest level in nine months.
But the index is still just seven points above the lowest reading on record, in January 2009.
And any reading below 50 indicates negative sentiment about the housing market.
The index hasn't reached 50 since April 2006, the peak of the housing boom.
